[New User with No Success]

Hey all,

I'm new to Flirc so there is a high probability I am doing something wrong.  However, I can't seem to figure out what that is.

My ultimate goal is to get my URC MX-990 to control my Nvidia Shield 2017.  My first attempt generally worked (except for the Back function) for about 24 hours, but suddenly it completely stopped responding.

So, I decided to just do some basic keyboard testing to see if I could make things work in Windows Notepad to make sure I was doing things correctly.  Unfortunately, I'm having no success.

Here is what I did after clearing the Flirc and starting from scratch:

1) I run the Flirc GUI and select Full Keyboard.

2) I select a key (the "A" for example), and press a button on my IR remote.

3) Flirc says it is recorded successfully.

4) I open Notepad and press the key on my remote corresponding to "A".... and *usually* nothing. Sometimes, if I push and hold or press multiple times, a random "a" will appear.  But none of the other keys work at all.

I tried this with a standard DirecTV remote just to make sure it wasn't something with the MX-990, but the result is the same.

Any ideas how to troubleshoot?

EDIT: I should mention I'm using Flirc 2.0 with firmware v4.9.3 and GUI v3.25.3
